At the touch of a button, the KOBIL SecOVID token calculates a numerical one-time password from more than one billion possible combinations, displays it on the screen and instantly forgets it as soon as the application is closed. Used in combination with a PIN number, the system offers unrivalled security.
Without a PIN the one-time password is useless, and without the token the PIN is useless. This is precisely the strength of two-factor authentication: knowledge (PIN) and possession (token).
